You will need coordination and patience whilst playing Cell, as you navigate the obstacles and collect diamonds. The game is controlled with the arrow keys (or WSAD keys) and the mouse, simultaneously. Oh, and the controls flip around too. Yeah, you will definitely need that patience I mentioned.

Get Adobe Flash Player. Embedded with the help of embed-swf.org.

There are 25 levels and yes, the game is possible to complete. It's just difficult and takes practise. Of course, maybe you're just not good enough to get to the end.
